Manufacturing is active all through
the New England States. especially in
The textile mills.
In Southern Arizona business of all
kinds is increasing in volume, and the
mining and cattle industries are as.
suming large proportions.
Eastern parties are making az
rangements for the establishment of
boiler and machine factories at Ta-
coma, w. T. The iron to be used will
come from neighboring mines.
BY means of an air-gun, Prof. G.
L. Mees has found that to drive straws
into pine boards and hickory bark. as
is often done by tornadoes, g velocity
of $50 to IT'S miles an hour is noces-

"A remarkable proof of the protect
tive instinct of birds is reported from
South America. In Chill the fruit of
the year is said to have caused the
death of many sheep and cattle when
fed to them in large quantities. The
birds, however. did not touch the fruit.
From this fact it is argued that the in
stnct of birds in respect &c fruit may
we'll guide man in regard to eating it;
and the further suggestion is made that
the condition of the fruit crop of par
ticular season may have something to
do with outbreaks of epidemic disease.

The remarkable industrial and
commercial progress made in the South
ern States during the past few years
has been widely noticed. An i'm
portant feature of this is found in
the comparative freedom from labor
troubles, which in nearly evory other
section of the country have caused so
much disturbance. Leading Southern
papers have recently called the atten-
ton of manufacturers and others to
this as an inducement to embark in
Southern business enterprises. and this,
with natural advantage at the South,
has induced many TO start in business
there. BrddStreet s.
According to recent experiments of
MN. HaurloG ana hlcnet, OF Whlch an
account has been given to tho French
Academy of Sciences, the ventilation of
the lungs is increased by muscular
labor. In moderate work the vcntila-
ton is more than sufficient for the ex-
erection of the carbonic acid produced,
and above all for the absorption of tho
necessary oxygen. In hard work the
proportions of carbnnic acid produced
and oxygen absorbed rise slightly the.
harder the work; but it is chiefly the
proportion of carbonic acid which in
creases. During cular exert;on the
ratio of carbonic acid produced TO
oxygen absorbed tends to become unity,
although normally it is less than unity.
